Hi
I want to write parallel version(on CUDA) of brute force for DES and RC4 and compare it to version on classic CPU. I would be very grateful if someone gave me some hints where I can some articles or materials about how to write brute force for these algorithms

The main observation that I wish to address, is that of the design strategy of which the majority of the family (i.e., MD4 family) of conventional hash functions are composed; this family consists of MD4, MD5, HAVAL, RIPEMD, SHA-1, and SHA-2, and the respective output length extensions of those, where applicable.

The specification of network authentication protocol only supply the Data Encryption Standard (DES) for encryption. For many years, the cryptographic community has regarded DES as providing inadequate security, mostly because of its small key size.
